The informations about a call are displayed via the Wazo Client on forms called
sheets. Sheets or customer info is a mechanism that allow the user to receive information
about a call in its client. There are many events that can trigger a sheet to be
displayed and there are many variables available for display.

The second step is to set the URL when the call is queued. To do that, we will
use a preprocessing subroutine. This is configured in the queue configuration :
go to Services ‣ Call center ‣ Queues and edit the
queue. Set the field Preprocessingsubroutine to setsheeturl (the same
as above).

The third step is to configure the sheet to open the wanted URL. Go to
Services ‣ CTI Server ‣ Sheets ‣ Models and create a new
sheet. Keep the default for everything except the Action tab, add a field and
set it to {dp-mysheeturl} (the same as above).

The fourth and final step is to trigger the sheet when the agent answers the
queued call. Go to Services ‣ CTI Server ‣ Sheets ‣
Events and link the event Agentlinked to the sheet you just created.

That’s it, you can assign agents to your queue, log the agents and make them
answer calls with the Wazo Client opened, and your browser should open the
specified URL.
